        \u4e09. Special Knowledge of Machine Components<\/strong><\/span><\/p>\n<\/div>

        Q6: What is the core structure and working principle of the A-03 trimming machine?<\/span><\/strong><\/p>\n

        A6:The equipment adopts a\u00a0<\/span>dual-blade synergistic<\/span><\/strong>\u00a0design:<\/span><\/p>\n

          \n
        1. \n

          Upper knife<\/span><\/strong>: High-speed rotating cutting, responsible for actively removing burrs;<\/span><\/p>\n<\/li>\n

        2. \n

          Lower knife<\/span><\/strong>: Driven rotation, cooperating with the upper knife to form a shearing action, guiding and assisting the cutting.<\/span>
          \nDuring operation, the operator lightly places the workpiece against the knife position. The high-speed cutting of the upper knife combined with the driven rotation of the lower knife easily and thoroughly removes any type of burrs and flashes. Through precise control of cutting angle and pressure, it ensures that the upper, sole, or product body is not damaged during the efficient trimming process.<\/span><\/p>\n<\/li>\n<\/ol>\n<\/div>

          Q7: What are the key points to pay attention to in daily maintenance of the A-03 trimming machine?<\/span><\/span><\/strong><\/p>\n

          A7:To ensure long-term stable operation and trimming accuracy, it is recommended to perform the following maintenance:<\/span><\/p>\n

            \n
          1. \n

            Lubrication<\/span><\/strong>: The machine is equipped with\u00a0<\/span>4 oil holes<\/span><\/strong>. It is recommended to add\u00a0<\/span>1 drop of engine oil<\/span><\/strong>\u00a0to each oil hole every\u00a0<\/span>2-3 hours<\/span><\/strong>.\u00a0<\/span>Important: DO NOT use sewing machine oil (needle oil), as it has a cleaning effect that will wash away the original lubricating film, causing component wear. Use ordinary automotive engine oil (such as that used for motorcycles or car engines) for lubrication and friction reduction.<\/span><\/strong><\/p>\n<\/li>\n

          2. \n

            Cleaning<\/span><\/strong>: Regularly remove debris and dust accumulated on the blade and machine body;<\/span><\/p>\n<\/li>\n

          3. \n

            Blade inspection<\/span><\/strong>: Regularly check whether the upper and lower knives are sharp. Replace or sharpen them promptly if worn or chipped to ensure trimming quality;<\/span><\/p>\n<\/li>\n

          4. \n

            Fastening check<\/span><\/strong>: Regularly check whether screws in all parts are loose to ensure operational safety.<\/span><\/p>\n<\/li>\n<\/ol>\n<\/div>

            Q8: What are the respective functions of the upper knife and lower knife on the A-03 trimming machine? Can they be replaced separately?<\/span><\/span><\/strong><\/p>\n

            A8:The upper knife is the\u00a0<\/span>actively rotating cutting tool<\/span><\/strong>, generating cutting force at high speed to remove burrs. The lower knife is the\u00a0<\/span>passively driven tool<\/span><\/strong>, which is driven to rotate when the workpiece contacts it, providing support and auxiliary shearing for smoother and more thorough trimming. Both the upper and lower knives are\u00a0<\/span>independently replaceable components<\/span><\/strong>. When a blade is worn or damaged, the upper or lower knife can be replaced individually without scrapping the entire set, effectively reducing maintenance costs. It is recommended that customers keep a spare set of knives on hand to reduce machine downtime.<\/span><\/p>\n<\/div>

            3. \n

              Trimming operation<\/span><\/strong>: The operator holds the workpiece (sole, upper, leather goods, etc.) and lightly contacts the knife position at an appropriate angle, moving smoothly along the burr edge to complete the trimming;<\/span><\/p>\n<\/li>\n

            4. \n

              Quality inspection<\/span><\/strong>: Check whether the trimmed product edge is smooth, free of residual burrs, and undamaged;<\/span><\/p>\n<\/li>\n

            5. \n

                \n
              1. \n

                Synergistic effect of upper-knife high-speed cutting + lower-knife driven rotation<\/span><\/strong>\u00a0concentrates cutting force at the burr position with minimal impact on the product body\uff1b<\/span><\/p>\n<\/li>\n

              2. \n

                Operator technique control<\/span><\/strong>: It is recommended that operators hold the product at a\u00a0<\/span>20-30 degree tilt angle<\/span><\/strong>\u00a0against the knife and move smoothly along the burr edge, avoiding excessive force or prolonged\u505c\u7559 at the same position\uff1b<\/span><\/p>\n<\/li>\n

              3. \n

                Blade sharpness<\/span><\/strong>: Keeping blades sharp effectively reduces cutting resistance and avoids\u62c9\u626f damage caused by dull knives\uff1b<\/span><\/p>\n<\/li>\n

              4. \n

                Applicable material range<\/span><\/strong>: The machine is designed for soft to medium-hardness materials (rubber, EVA, PU, leather, etc.).
